I recently got a Cisco Flip camera. It’s awesome, but OSX has a major problem that it launches iPhoto (in addition to the Flip software) when I plug in the device to the USB port.
This means that two applications are busily indexing the contents of a USB device every time I want to use it.
To inhibit:
Plug device in → → Launch Image Capture → Select the device → Change the drop-down for “When device is connected” from iPhoto to do nothing → Be happy.
